基于树模型(Tree-based models)的机器学习——上篇 基于树的模型(Tree-based models)有一些优点,如可解释性强、使用方便以及准确率高。该模型可用于拟合人们的决策行为,因变量既可以是分类变量,也可以是连续变量。 一、决策树 决策树(decision trees)是基于树的模型中最基础的概念,它可用于解决分类或回归问题。 1.1 决策
The output of the RT and REP tree models is evaluated using performance measures including accuracy (Acc), Matthews correlation coefficient (Mcc), precision (Prec), recall (Rec), and F-score. The applications of the aforementionedmethods for predicting slope stability are compared to one another ...
The inductive bias(also known as learning bias) of a learning algorithm is the set of assumptions that the learner uses to predict outputs of given inputs that it has not encountered. 详细讨论可参考知乎问题如何理解Inductive bias? 正文: 作者主要是整理了45个表格类数据集来做一个统一的比较基准,...

It consists of two parts: (1) the base learners, including three tree-based models (RF, XGBoost, and Light Gradient Boosted Machine (LightGBM)), which provide the primary O3 estimations (Section 2, Supporting Information); and (2) the meta learner by SIDLM that combines the primary O3 ...
At a high level, we formulate robustness verification problem of tree based models into a max-clique enumeration problem on amultipartitegraph with boundedboxicity. We develop a hierarchical scheme such that the max-cliques are enumerated in a level-by-level manner, which allows us to quickly fin...
We introduce a symbolic model checking procedure for Probabilistic Computation Tree Logic PCTL over labelled Markov chains as models. Model checking for probabilistic logics typically involves solving linear equation systems in order to ... C Baier,EM Clarke,V Hartonas-Garmhausen,... - International...
(^2\). These measurements are highly correlated and thus the forecast performance of the statistical models would not increase when using all wind speed measurements. To this end, we conduct a manual preselection of the observations at VIE to generate a highly informative predictor setup. This ...

treeshapis an efficient answer for this question. Due to implementing an optimized algorithm for tree ensemble models (called TreeSHAP), it calculates the SHAP values in polynomial (instead of exponential) time. Currently,treeshapsupports models produced withxgboost,lightgbm,gbm,ranger, andrandom...
